Description

Technical Field

[0001] The utility model relates to the field of zinc pot equipment, in particular to a device for removing caked bottom slag of an aluminized zinc pot. Background Art

[0002] The hot-dip aluminized zinc steel plate is a new product developed on the basis of hot-dip galvanized products. Its formula composition is 55% aluminum, 43.5% zinc, and 1.5% silicon. Since this aluminum-zinc liquid ratio will cause various zinc-iron compounds to be produced during production and sink to the bottom of the pot to become bottom slag, over time, the bottom slag will become very hard in the pot (that is, the "caking" phenomenon occurs), which is very difficult to break and remove, restricting the use of the immersion roll, and thus affecting the normal production of the hot-dip aluminized zinc line.

[0003] Furthermore, in the prior art, the methods of nitrogen purging and zinc addition replacement are obvious in dealing with floating slag or newly generated bottom slag. However, the main component of the caked bottom slag is FeZn7, with a high hardness of HD = 454. The existing methods of nitrogen purging and zinc addition replacement basically have no treatment effect and cannot remove the bottom slag. In order to prevent the increase of caked bottom slag from causing the immersion roll to not be able to be normally put into the pot for use, the production line adopts the operation of fishing for the bottom slag in each roll change cycle. However, the bottom slag is massively caked at the bottom of the pot, and only a small amount of bottom slag can be fished out by using a grab bucket, and the problem of caked bottom slag cannot be completely solved.

[0004] Therefore, the applicant urgently needs to seek technical solutions to solve the above technical problems. Summary of the Invention

[0005] In view of this, the purpose of the utility model is to provide a device for removing caked bottom slag of an aluminum pot for a hot-dip aluminized zinc line. A mobile operation trolley platform is built above the aluminum pot, and the bottom slag is broken by a pneumatic pick-pick assembly, which can be effectively carried out without affecting normal production. The slag removal operation is carried out when switching the process, avoiding the difficult factors of the bottom slag being difficult to remove after cooling and caking, effectively removing the caked bottom slag of the aluminum pot, with low slag removal cost and remarkable effect.

[0022] The embodiment of the present utility model discloses a hardened bottom slag removal device for an aluminized zinc pot (this application is also referred to as "aluminum pot", and the two are synonymous, referring to the aluminum pot in the aluminized zinc line). Channel steels for serving as guide rails are respectively fixedly arranged on both sides in the left-right direction at the upper end of the aluminized zinc pot, and a mobile operation trolley is slidably installed on the channel steels to realize displacement in the front-rear direction of the aluminized zinc pot; wherein, a limiting part is fixedly arranged at the bottom of the mobile operation trolley, and the limiting part has a preset limiting height from the bottom of the aluminized zinc pot; the mobile operation trolley is configured with a pneumatic pick-pick component for the operator to operate, and the pneumatic pick-pick component is extended into the aluminized zinc pot to impact and break the hardened bottom slag, so that part or all of the hardened bottom slag in the aluminized zinc pot is removed.

[0023] In order to enable those skilled in the art to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1As shown, the internal dimensions (length * width * height) of the aluminum pot 1 are 3200mm * 3200mm * 2300mm. The channel steel 2 (specifically, 10# channel steel is selected in this embodiment) is welded to the upper end of the aluminum pot 1 and serves as the track for the two side moving operation trolleys in the left - right direction. By combining double universal wheels and a set of directional wheels, the trolleys are slidably installed on the channel steel 2, enabling displacement in the front - rear direction of the aluminum pot 1. The limiting round steel 3 is welded to the bottom of the moving operation trolley, and the distance between it and the bottom of the aluminum pot 1 is 300mm (which is the preset limiting height for the moving operation trolley), playing a limiting role when measuring or breaking the caked bottom slag to prevent the pneumatic pick - pick bit assembly from damaging the bottom of the pot.

[0025] In this embodiment, a heat - insulating plate 4 is fixedly installed at the bottom of the moving operation trolley to achieve heat insulation between the moving operation trolley and the aluminum pot 1. Further preferably, in this embodiment, heat - insulating cotton is laid inside the heat - insulating plate 4 to achieve the effect of isolating the heat of the aluminum pot.

[0026] Please further refer to Figure 2 As shown, in this embodiment, the overall dimensions (length * width * height) of the moving operation trolley are 5700mm * 1300mm * 1800mm, spanning across the aluminum pot 1 in the left - right direction. Protective baffles 5 are respectively arranged at both ends of the moving operation trolley in the front - rear direction, and a hollow - shaped guardrail 6 is further arranged on the outer side of each protective baffle 5. Among them, the installation height of the baffle 5 is 1000mm, which is convenient for pneumatic pick operation; the installation height of the guardrail 6 is 1800mm, and it adopts a hollow design. The guardrail 6 is equipped with a kick - plate, which is firm and reliable, and the bottom plate is anti - slip, for the safety protection of personnel during operation.

[0027] The working process is further described in combination with this embodiment: The moving direction of the moving operation trolley is the front - rear direction. When the moving operation trolley is moving, there are no operators on the platform. Before slag removal, a stainless - steel chain is used to tie the pneumatic pick to prevent the pneumatic pick and the pick bit from falling into the aluminum pot 1. When removing slag, first, a detector is used to detect and draw a distribution map of the bottom slag in the aluminum pot 1 (please refer to Figure 3 As shown). According to the detected trend of the bottom - slag distribution and combined with the depth dimension of the aluminum pot 1, after raising the temperature of the aluminum pot 1 by 50 - 100℃ on the basis of the normal production temperature, pneumatic pick slag - removal operation is carried out. Specifically, it is recommended to take one column from left to right and orderly break the caked bottom slag in the aluminum pot 1 column by column, and then specifically remove the bottom slag in different height areas. The pneumatic pick drives the pick bit to vibrate and strike the bottom - slag block to break it.

[0028] Specifically, according to the volume of the aluminum pot 1, the maximum limit of the pickaxe is designed to be 2300 mm, which is equal to the highest distance from the pot body to the pot rim. Subtracting the limit height of 300 mm of the mobile operation trolley and adding the height of 100 mm from the liquid level to the pot rim, the total is 1900 mm, ensuring that it is within the safe slag removal height limit and preventing damage to the refractories of the aluminum pot 1. During the operation, 4 operators can cooperate with each other. Among them, 2 are responsible for moving the position of the pickaxe, 1 is responsible for operating the pneumatic pick, and 1 assists in lifting and lowering the pneumatic pick (including the pneumatic pick chain) and fixing the air pipe.

[0029] After the operation of impact-crushing the agglomerated bottom slag in the aluminum pot 1 is completed (that is, the agglomerated bottom slag in the aluminum pot 1 is removed), then it is removed by the method of the existing technology. Specifically, first, the aluminum pot 1 is purged with nitrogen to blow up the bottom slag in the corner of the aluminum pot 1 and drive it to the area with less bottom slag. After precipitation for twenty minutes, a crane is used to lift a large torque grab bucket. After the cylinder connecting valve platform is tested for operation, slag fishing operation is carried out to grab the zinc slag into the aluminum-zinc liquid bucket. This part is common knowledge for those skilled in the art and does not belong to the innovative content of this application, so it will not be specifically elaborated here.

[0030] In summary, this embodiment overcomes the defects of the existing slag removal technology method. A mobile operation trolley platform is built above the aluminum pot, and the bottom slag is destroyed through the pneumatic pick-pickaxe assembly, which can be effectively carried out without affecting normal production. The slag removal operation is carried out when switching the process, avoiding the difficult factor that the bottom slag is difficult to remove after cooling and solidifying, effectively removing the agglomerated bottom slag of the aluminum pot, with low slag removal cost and remarkable effect.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model.
